Hacking the HP 5406zl…

The HP 5406zl

The venerable HP 5406zl.  This switch has been around for many years, in fact, it was introduced back in 2004.  Over time, this switch has seen a number of upgrades, and the current base model 5406zl’s provide 379Gbps of non-blocking goodness.  A while back I acquired one of these to replace the Cisco SG200-26 I had.  The 5406zl is a fully modular switch, and great deals on eBay can be had, if you know where and what to look for.

One of the modules for the 5406zl is the Advanced Services Module.  I have two of these.  They are x86 servers on a blade, letting you run VMware, Hyper-V or Xen.  Normally, you have to buy them from HP pre-configured.  The reality is you do not, you just have to be a bit creative.

These blades J4797A, come with a dual core 2.53Ghz, 4GB RAM and a 256GB 2.5″ hard drive.  You can easily upgrade the RAM from 4 to 8GB (it is DDR3 SODIMM).  You can also swap the Hard drive for a SSD.

I have a J4797A which is supposed to run Citrix XenServer.  I simply upgraded the RAM, and installed VMware 5.1 to the SSD, and viola, I was able to get a $2000 VMware blade for around $250CAD all in.  While not super speedy, these blades work great for DNS, Firewall and TACACS.  They even come with HP’s Lifetime Warranty.

Oh, and if you did not hear, the latest K15.16.0006 (now .0008) firmware, enables the “Premium” features for free.  Even more reason to find one of these switches on eBay.
